Estou escrevendo um arquivo JSON que seria lido por um programa em Java. O fragmento é o seguinte ...

{
  "testCases" :
  {
    "case.1" :
    {
      "scenario" : "this the case 1.",
      "result" : "this is a very long line which is not easily readble.
                  so i would like to write it in multiple lines.
                  but, i do NOT require any new lines in the output.
                  I need to split the string value in this input file only.
                  such that I don't require to slide the horizontal scroll again and again while verifying the correctness of the statements.
                  the prev line, I have shown, without splitting just to give a feel of my problem"
    }
  }
}
